Phys. Rev. Lett. 73, 1477–1480 (1994)Neutron Multiplicities and Yields of Correlated Zr-Ce and Mo-Ba Fragment Paris in Spontaneous Fission of 252CfReceived 10 June 1994; published in the issue dated 12 September 1994 High resolution γ-γ and γ-γ-γ coincidences in the spontaneous fission of 252Cf were measured. Relative yields and neutron multiplicities from zero up to 10 were extracted directly for the first time in fission for the Zr-Ce and Mo-Ba correlated fragment pairs. The 0, 8, and the new 10 neutron emission yields for Mo-Ba are significantly larger than those reported previously for total 252Cf spontaneous fission. Our results demonstrate that the use of this high resolution γ-γ-γ coincidence technique can provide important, previously inaccessible data on fission. © 1994 The American Physical Society URL:
